SPOOL FOR WINDING BARBED FENCING.

. SPECIFICATION forming part of Letters Patent No. 255,147, dated March 21, 1882.

Application filed December 27, 1881.

'To all whom it may concern State of Massachusetts, have invented certain new and useful Improvements in Spools for Winding Flat-Strip Barbed Fencing; and I declare the following to be a description of my said invention sufficiently full, clear,and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of my present invention is to provide a spool or device for winding flatstrip barbed fencing which will insure the convenient and regular winding and unwinding of the strip without liability of tangling or interlocking the barbs, said spool being more especially for use in connection with galvanizing apparatus, or for receiving the strip from the barbingmachines and delivering it to the galvanizing apparatus after the barbs have been attached thereto, it being quite desirable that the delivery of the strip should proceed at a uniform tension, and without the snapping or shaking effect which occurs when the barbs become caught and are then suddenly released, and also to avoid loosening the barbs or slipping them upon the strip or ribbon-wire. before they hecomepermanently fixed by means of the galvanizing metal. which, while being of comparatively small diameter, shall contain a large quantity of the fence material. These objects I attain by a spool device constructed as herein shown and described.

In the drawings, Figure 1 is a side view of my improved spool'for flat-strip barbed fencing. Fig. 2 is a transverse section at line to 10, Fig. 1; and Fig. 3 is a longitudinal section at line to m, Fig. 2.

My improved spool consists of a central cylinder or barrel, A, two end disks or heads, B B, and a greater or less number ofintermediate flanges or disks, 0, combined in suchmanner as'to form a series of grooves or spaces of the proper width to receive and support the fence-strip or metal ribbon D, with its barbs d, in a single volute or roll, while the said intermediate disks are provided with inclines, guides, or passways E for transferring the Another object is to make aspool.

strip from the outer part of one groove to the inner part of the groove adjacent thereto without injuring the fence-strip or interfering with the wound portions, so that the entire spool can be filled by a continuous strip or ribbon, and the same or any portion thereof unwound and rewound with convenience and facility, and without the barbs catching or looking onto the adjacent coils or against each other. The end disks or heads, B, are made full circles, while the intermediate disks or flanges, 0, have a slit or opening at one side, which forms the passway E. The bottom 0 of the-passway is made with a flat surface for supporting the fence-strip D, said fiat surface commencing with a rounded cor ner,f, at the periphery of the disk 0, and extendinginward to meet the barrel A tangent, or nearly so,

with its surface, so that the fence-strip will v that the fence-strip can pass across from one I groove to the next at an easy inclination.

In the present instance a spool with four grooves, F F F F, or winding-spaces is shown but, if desired, any number ofgrooves may be used, whether more or less than hereinillustrated. The spool may be made entirely of metal, or it may be formed of wood, with the sides of the disks B and flanges O lined with sheet metal. The barbed fencingstrip is wound upon the spool until the first groove, F, is filled. It is then carried, by shifting the position of the spool laterally or otherwise, across the passway F into the second groove, F as indicated, which groove is then filled, and so on through the entire series of grooves. The spool, being of comparatively small diameter in proportion to the quantity of material which it can contain, does not give excessive strain on the operating mechism when winding near the periphery, as would occur with a spool having only a single groove and of sufficient diameter to contain an equal quantity of the barbed fencing-strip.

If desired, the fencing-strips could be put up for the market on this style of spool; but the chief utility of my invention is for winding and rewinding the barbed strips during the various processes incident to the manufac- 2.
